Uncertainties in the model gave the scientists only a broad estimate of ice loss in the East Antarctic ice sheet of between 5bn and 109bn tonnes a year.
该模型的不确定性导致其结果只能给科学家一个大致的估计：南极东部冰盖的消融速度介于每年50亿吨和1090亿吨之间。
The amount of loans treated this way is unclear because nobody centrally collates the data, and Fitch says its three trillion yuan estimate for off-balance-sheet credit is rough.
这种方式的贷款总量还不清楚，因为没有人集中的整理这些数据，而且惠誉国际评级公司说的负债表之外的3万亿人民币的估计也只是猜测。
Loan officers are not allowed to hand customers the rate sheet but call me and I will send you a good faith estimate with par pricing.
贷款人员均不得向客户手率表，但要求我，我会送你一个善意估计杆定价。
It is necessary to combine the mass balance with the ice sheet dynamics and to develop the couple model of ice-ocean-atmosphere for accurate estimate of the mass balance state and its variability.
准确地评判物质平衡变化趋势则需将物质平衡与冰体动力学结合起来，并建立冰-海-气耦合模型。
